The control unit 130 is configured to detect completion of execution of one block of the NC program.
In the one-block stop mode, the machining operation is automatically stopped when the NC program reaches the block completion position, and after the stop, the next one block is executed by operating the switch button 112 on the operation panel 110. It becomes possible. The operator can debug the NC program one block at a time by setting the control unit 130 in the one-block stop mode, and can confirm the operation state of the spindle 161, the rear spindle 163, and the tool 162.

さらに、本実施例の工作機械100は、1ブロック停止モードにおいて、1ブロックの完了を報知する報知手段140を備えている。
報知手段140は、制御部130と、照明器164とから構成されている。
そして、制御部130が、1ブロックの完了を検知し加工室160の照明器164の発光量を変化させるように構成されている。
これにより、窓167を介して加工室160内を注視している作業者が加工室160の照明器164による加工室160内の照度の変化に気づき、NCプログラムの1ブロックの実行完了を知ることができる。
Furthermore, the machine tool 100 according to the present embodiment includes a notification unit 140 that notifies the completion of one block in the one-block stop mode.
The notification unit 140 includes a control unit 130 and an illuminator 164.
And the control part 130 is comprised so that the completion of 1 block may be detected and the light emission amount of the illuminator 164 of the processing chamber 160 may be changed.
As a result, an operator gazing inside the processing chamber 160 through the window 167 notices a change in illuminance in the processing chamber 160 by the illuminator 164 of the processing chamber 160, and knows that execution of one block of the NC program has been completed. Can do.

以下、報知手段140の動作についてより詳しく説明する。
図3に示すように、ステップS11では、制御部130が、現在選択されているモードが1ブロック停止モードか否かを判定する。
1ブロック停止モードであると判定した場合はステップS12へ進み、否であると判定した場合はシーケンスを終了する。
Hereinafter, the operation of the notification unit 140 will be described in more detail.
As shown in FIG. 3, in step S11, the control unit 130 determines whether or not the currently selected mode is the 1-block stop mode.
If it is determined that the one-block stop mode is set, the process proceeds to step S12. If it is determined that the determination is NO, the sequence is terminated.

ステップS12では、制御部130が、NCプログラムの実行が1ブロック完了したか否かを判定する。
1ブロックの完了を検知した場合、ステップS13へ進み、否であると判定した場合は1ブロックの完了を検知するまでステップS12を繰り返す。
In step S12, the control unit 130 determines whether or not the execution of the NC program has been completed for one block.
When the completion of one block is detected, the process proceeds to step S13, and when it is determined as NO, step S12 is repeated until the completion of one block is detected.

ステップS13では、制御部130が照明器164の点灯制御等によって照明器164の発光量を変化させる。
1ブロック停止モードは、手動実行モード及び自動実行モードの両方の状態で設定することができる。特に手動実行モードの状態で、1ブロック停止モードが設定されている場合、作業者は、窓167から加工室160内を見て主軸161や工具162等の位置を確認しながら手動パルスハンドル111を操作している場合、作業者の視線は加工室160内に向いている。
従って、窓167を介して加工室160内を見ている作業者が加工室160の照明器164による加工室160内の照度の変化に気づき、1ブロックの実行が完了したことを容易に知ることができる。
In step S <b> 13, the control unit 130 changes the light emission amount of the illuminator 164 by lighting control of the illuminator 164 or the like.
The one block stop mode can be set in both the manual execution mode and the automatic execution mode. In particular, when the 1-block stop mode is set in the manual execution mode, the operator looks at the inside of the machining chamber 160 from the window 167 and confirms the position of the spindle 161, the tool 162, etc., and moves the manual pulse handle 111. When operating, the operator's line of sight is directed into the processing chamber 160.
Therefore, an operator looking inside the processing chamber 160 through the window 167 notices a change in illuminance in the processing chamber 160 by the illuminator 164 of the processing chamber 160, and easily knows that one block has been executed. Can do.

この際の照明器164の発光量の変化は、例えば、照明器164の発光量を1ブロックの終わりに達する前と比べて小さくする。
これにより、加工室160内が、1ブロックの実行完了後に完了前と比べて暗くなるため、作業者は加工室160内の照度の変化に容易に気づく。
また、照明器164を点滅させてもよい。
これにより、1ブロックの実行完了前の点灯した状態から完了後に点滅した状態となるため、作業者は加工室160内の照度の変化に容易に気づく。
At this time, a change in the light emission amount of the illuminator 164 is, for example, made smaller than that before reaching the end of one block.
As a result, since the inside of the processing chamber 160 becomes darker than after the completion of execution of one block, the worker easily notices a change in illuminance in the processing chamber 160.
Further, the illuminator 164 may blink.
As a result, since the lighting state before the completion of execution of one block is changed to the blinking state after completion, the operator easily notices the change in the illuminance in the processing chamber 160.

作業者は、1ブロックの実行が完了したことを知ると、操作パネル110のスイッチボタン112を操作して、加工室160内の照明器164の発光量を1ブロックの実行完了前の状態に戻すこともできる。   When the operator knows that the execution of one block has been completed, the operator operates the switch button 112 of the operation panel 110 to return the light emission amount of the illuminator 164 in the processing chamber 160 to the state before the execution of one block is completed. You can also.

なお、作業者が、NCプログラムの次の1ブロック分の動作を確認したい場合、操作パネル110のスイッチボタン112を操作するとともに手動パルスハンドル111を操作して次の1ブロックの実行を開始する。
つまり、ステップS11〜S13を繰り返す。
When the operator wants to confirm the operation of the next block of the NC program, the operator operates the switch button 112 of the operation panel 110 and operates the manual pulse handle 111 to start execution of the next block.
That is, steps S11 to S13 are repeated.

このようにして得られた一実施例である工作機械100は、材料の加工を行う加工室160と、この加工室160内の照明器164と、NCプログラムに基づいて加工作動を制御するNC装置である制御部130とを備え、制御部130が、手動操作部の一例である手動パルスハンドル111の操作に応じて発生するパルス信号により、加工作動を実行させる手動実行手段131と、NCプログラムを1ブロック実行して停止する1ブロック停止モードとを有し、工作機械100において、1ブロック停止モード中に、手動実行手段131によって手動で加工作動を実行する際に、1ブロックの完了を報知する報知手段140を設け、報知手段140が照明器164から構成されている。
そして、報知手段140を、照明器164による加工室160内の照明状態を可変させることよって報知するように構成したことにより、1ブロック停止モード中に手動パルスハンドル111を回転操作する作業者が、加工室160外の操作パネル110を見ることなく、手動パルスハンドル111の操作中に監視チェックするべき加工室160内の動作部の動作等、例えば工具162や工具162を保持する刃物台、主軸161、背面主軸163等の動作、加工室160内のワークの状態等を見ながら、プログラムの1ブロックの実行完了を、加工室160内を見て知ることができる。
